INSULATOR-BASE.

Application filed. January 8, 1913.

- specification...

In the present invention, the insulatorsupport is equipped with means for engaging the post or bracket arm, these means being so constructed the application thereof to "I the post or bracket arm will weaken the same to a minimum extent.

The invention aims to provide a base for an insulator, so constructed that it can be shifted along the bracket arm or post to permit the running of additional lines.

Another object of theinvention is to provide a support for an insulator which will bring the conductor, relatively close to the bracket arm or post, the strain being distributed equally and evenly.

Another object of the invention is to provide a base for an insulator, so constructed that snow and ice may accumulate upon the bracket arm or support, without coming in contact with the wire.

\Vith the foregoing and other objects in view, which will appear as the description proceeds, the invention resldes 1n the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings :-F igure 1 shows the invention in top plan; Fig. 2 is an end elevation; Fig. 3 is a horizontal section on the line 33 of Fig. 2; Fig. i is a vertical sec-v tion on the line tl of Fig. 1; Fig. 5 is a plan of one face of the support; Fig. 6 is a plan of the opposite face of the support; Fig. 7 is an end elevation showing a modified form of the invention; and Fig. 8 is a side elevation of the structure shown in Fig. 7

1n carrying out the invention, and referring particularly to Figs. 1 to 6, inclusive, an insulator support is shown, the same comprising an arcuate body denoted Specification of Letters Patent.

by the numeral 1, and preferably fashioned from metal. One face of the body 1 is conoaved and is provided with transverse corrugations 2, adapted to interlock with similar corrugations 3 upon an insulator 4-, comprising separable parts 5. At its end, the body 1 is equipped with transverse ribs 6, adapted to receive tie wires 7 which, passing around the parts 5 of the insulator 4;, tend to hold the parts of the insulator together, and to hold the insulator, as an entirety, upon the insulator support. The body 1 is provided at each side with a projecting lug 8 located between the ends of the ribs 6 and extended beyond the ends of ribs. Owing to the fact that the lugs 8 pro ject beyond the ends of the ribs 6, as shown at 9, the tie wires 7 are protected, as will be understood best when Fig. 2 is examined. The lugs 8 are terminally provided with transverse heads 10. Referring to Fig. 5

I it will be seen that reinforcing flanges 11,

disposed parallel to the ribs 6, are formed integrally with the body 1, with the lugs 8 and with the heads 10. The heads 10 are concaved as indicated at 12, and the edges of the flanges 11 are similarly concaved, to engage with a supporting post denoted by the numeral la. Securing means are connected with the ends of the heads 10, the securing means in the present instance taking the form of U-bolts 15 which pass around the post 14, there being nuts 16 upon the ends of the U-bolts 15, the nuts being adapted to bear upon the ends of the heads 10.

The insulator hereinbefore described is of the pole type, but it is within the prov ince of the invention to fashion the structure in such a manner that it may be assembled with a horizontally disposed bracket arm.

Referring to Figs. 7 and 8, the parts of the structure remain as hereinbefore described, saving as specifically modified. In Figs. 7 and 8 the tie-holding ribs are indicated at 17, the lugs at 18, the ties at 19, the two-part insulator by the numeral 20, and the heads by the numeral 21. In this form .of the invention, the modification consists in providing the heads 21 at their ends with depending ears 22 adapted to extend along opposite sides of the bracket arm 23. As before, support-engaging means are assembled with the heads, the support-engaging means in the present instance com- 3 prising bolt and nut structures 2% Which are passed through the bracket arm 23 and through the ears 22.

It will be seen that, in both forms of the invention, should the insulators become broken, the tie Wires which serve to hold the insulators upon the support Will still be effective to retain the conducting Wire which, in Fig. 1, is denoted by the numeral 25.

In both forms of the invention, the tie wires are protected through the cooperation between the lugs 8 and the ribs 6, as herein before explained, and in both forms'of the invention the ribs 11 serve to reinforce the structure, and constitute means for receiving, in the one instance, the post 14, and in the other instance, the bracket arm 28.

As shown best in Fig. 5, the base of the insulator comprises in a one piece structure, a trough-shaped support engaging body and a trough-shaped insulator receiving member disposed transversely of the body and intersecting the body to form in the body, opposed recesses R adapted to re-- ceive a spike or other projection which, being driven into the pole or arm on which thebase is mounted, serves to prevent the base from rotating. 7

Having thus described the invention, What is claimed is As an article of manufacture, an insulator base comprising in a one-piece structure, a trough-shaped, support-engaging body, and a trough-shaped, insulator receiving-member disposed transversely of the body and intersecting the body, to form in the body, opposed, support engaging recesses.

In testimony that I claim, as administratriX of the estate of FREDERIC A. WARREN (deceased) the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
